It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a finegrained rock while gabbro is a coarsegrained rock.

The dividing line between fine and coarse aggregate is the 3/8inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1).

Very coarse grained rocks are undesirable because of poor abrasion resistance. Some igneous rocks may have soluble minerals like zeolite; also, in foundations, weathered igneous rocks should not be used. In the case of sedimentary rocks, the source of rock is important.

Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and .

Aggregate produced from rock, gravel, metallurgical slag or synthetic materials may be used provided the particular criteria set out for the aggregate are met. AS sets out the requirements for the quality of a material source and the properties required of the coarse aggregate.
